will do should be putting it to the test this comming saturday going to a comp down in nevada 

[mel80]

bank worked great only ever saw voltage drop by 1-2 tenths from charging voltage as my alt heats up it drops voltage so when cold it was charging at 14.4 and i saw 14.2/3v when its hot i see 13.8 for charging voltage and only dropped to 13.6 at the lowest

Sick dude. Is that with 1 or 2 of the 148ah lev60 banks?

[mel80]

that is with single 148ah bank im going to step it up to 3 banks here soon as im switching form the five recoil 1200.1 amps to five slapz audio shock 5ks 

[mel80]

big update today i went up to jones subwoofer solutions today to do some testing and learned alot 

first up we did some testintg to see impedance at various frequencys 

 

starting at 50 hz imp is 1.6 ohms @ 40 hz were at 2.8 ohms and at 30-20 hz were holding on at anywere from 4.0-4.4 ohms 

 

so we put this think on a meter as well 

20 hz burp netted me a 150 on the glass @ 372w per sub 

30 hz burp netted me a 153 on the glass at about 450w per sub 

some changes ill be making

 im currently running 113 sqinch of port at 28hz tuning

im going to redo the port to around 175sq inch with the low tuning  

 

#2

need more power and alot of it 

recoil amps are comming out and at first im going to wire all 5 subs series parrel for an .8 ohm load on a single md12000.1 half ohm model , at some point this season im going to add a second matching md12k and wire 5 coils per amp at .4 ohm 

 

#3 need to finish sealing the wall , but along with this i am doing a wood roof as ive already separated the roof skin from all the supprt braces , while im at it im going to do a wood floor as well 

 

with theese changes ill be looking to be a solid competitor in monster and cyclone/typhone classes
